Battery breather vent

Post by reloader »

Hi,
Has anyone any idea where the vent hose for the battery is routed.
I seem to have a blockage 800mm in. Pipe could be trapped somewhere in wheel arch?
I don't have the kit to dismantle the offside front to trace it myself.
Was going to pull as much as possible back then cut and refeed?
Thanks for any help

Big syringe from the chemist, try blowing it through, I would not pull it out, you might never get it back in, I use strimmer line for cleaning out the sun roof drains, could try that

Thanks for your suggestions Waylander.
Tried various strimmer thicknesses, guitar strings - all to no avail.
There is a big blockage - when I pulled the hose off the battery, there was a lot of pressure released. Just glad the battery didn't rupture in there!

Cheers

Try a straightened out coat hanger, next level

Or it is really crimped somewhere, I still would not pull it out

Thanks again Waylander
There are too many bends just to get to the grommet within the 'frunk'.
The coat hanger will just poke through the tube - at the first bend.
Spoke to an indi and they suggested not connecting the pipe to the battery until its on a ramp - "it wont harm", then I can investigate where its blocked and sort it.

Most modern batteries don’t have breathers, one on my bike does not, nor the one in my 968

New battery arrived with little red plug and a warning to remove immediately.
Going with indi for now - until I can have a butchers around, by leaving battery not connected to venting pipe.

There is plenty of ventilation under the bonnet.

Cheers
